While running the WEI test on the Windows Vista Installation I receive scores of 5.9, 5.5, 5.9, 5.9, 5.4 - However, running the same WEI test on the Windows 7 installation I recieve scores of 7.1, 7.1, 7.3, 7.3, 5.4

Both tests were run on freshly installed copies. Each with DirectX 11, Latest ATi drivers & Catalyst installed, all Windows Updates installed. I understand that regardless of this my score will remain 5.4 due to my rather lacking hard drive. But im curious as to why there is such a large difference in Processor, Memory and Graphics scores.

Is it possible that it is simply down to the fact that Windows 7 deals with 64-bit systems better than its predecesor, or is there another underlying problem at work which could be tested and/or rectified?

Thanks in advance.

[sorry but im unsure whether this should reside in Hardware Hangout, or the Windows forums. As it is unclear whether it is regarding the actual hardware its self or the operation of the Windows Experience software]
